Abstract

fetched live from OpenAlex

This article researches a relatively new suicide method advanced by right-to-die organizations: oxygen deprivation by breathing helium inside a plastic hood. The article begins with a review of the role of the coroner and the history of oxygen deprivation with helium; it then examines 20 Judgements of Inquiry (JOI) by British Columbia coroners into this form of suicide. The JOI were obtained through the Freedom of Information and Protection of Privacy Act and cover the period of 1999 to 2007. Findings raise concerns about the coding system used by coroners as well as adherence to internal documentation guidelines. The British Columbia Coroners Service (BCCS) has a public safety mandate to investigate all unnatural deaths and to make recommendations to prevent deaths in similar circumstances. It is a concern that BCCS has no recommendations to prevent suicides by oxygen deprivation with helium. More in-depth, systematic research is recommended to determine the prevalence of suicide by oxygen deprivation and to develop strategies to benefit public health and safety.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
